How Much Do You Know About RV Power Inverter?

Installing a vehicle inverter brings much convenience people's life, it can help people to get the power at the given voltage and frequency in the limited space of the car. At present, the vehicle inverter has not been fully popularized in many countries, but people have already felt the importance it has.

The on-board power supply is a commonly used car electronic product. Through it, we can use it to power multiple appliances in the car, such as TV sets, laptop computers, electric drills, medical equipment, military vehicle equipment, etc,. The vehicle inverter can be divided into two types: sine wave inverter and square wave inverter. The former can provide uninterrupted high-quality alternating current and can adapt to any load, but its technical requirements and costs are high, and the circuit structure is relatively complex. The quality of the alternating current provided by the latter is crossed, and the load capacity is poor, so it cannot be connected to inductive loads. Although there are many shortcomings, it has low technical requirements, small size, simple circuit and low price. Combining the above two advantages, the car power supply sold by our company adopts the advanced pure sine wave technology. Compared with the square wave, it can not only drive the inductive load, but also has small size, light weight and high efficiency, stable output voltage, high reliability, perfect protection function and so on. Now it has become the mainstream product on the market.

The on-board inverter output through the cigarette lighter can be 20W, 40W, 80W, 120W, up to 150W power specifications, and some larger power inverters must be connected to the battery through the link cable. By connecting household appliances to the output of the power converter, you can use a variety of appliances in your car as easily as you do at home. The electrical appliances that can be used are: mobile phones, notebook computers, digital video cameras, cameras, lighting, electric shavers, CD players, power tools, car refrigerators and so on.

The whole circuit of the vehicle inverter can be divided into two parts.The function of the first part is to convert the 12V direct current provided by the car battery, etc. into an alternating current of about 30kHz-50kHz and 220V through high-frequency PWM switching power supply technology.

The role of the second part of the circuit is to use bridge rectification, filtering, pulse width modulation and switching power output and other technologies to convert the 30kHz-50kHz, 220V alternating current into 50Hz, 220V alternating current. 

Firstly, make sure to use the vehicle inverter strictly in accordance with the instructions of the user manual. Secondly, the output voltage of the inverter power supply is 220V alternating current, and this 220V power supply is really a small space and is in a movable state, so be careful. It should be placed in a safer place (especially for children) to prevent electric shock. When not in use, it is necessary to cut off its input power. Third, do not place the inverter in direct sunlight or near the outlet of the heater, and the working environment temperature of the vehicle inverter should not exceed 40°C. Fourth, the inverter will heat up when working, so do not place objects near or on it. Fifth, let the inverter be far way from water or moisture.
